IMPROVEMENT IN SWITCHES FOR CHANGING GAUGE OF CARS.

The Schedule referred to in these Letters Patent and making part of thesaine.

To all whom it 'may concern.:

Be it known that I, THOMAS Foce, of St. Marys, in the Province ofOntario and Dominion of Canada, have invented a new and improved Switchfor Changing Gauge of Cars; and I do hereby declare thatthe following isa full, clear, and exact description thereof, which will enable othersskilled in the art to make and `use the same, reference being had to theaccompanying drawing forming partei' this specification, in which-Figure 1 represents a plan or top View of my improved switch applied toa double-gauge track.

Figure 2 is a transverse vertical section of the same.

Similar letters of reference indicate corresponding parts.

Thisinvention has for its object to provide a switch by means ot' whichcars having adjustable wheels can be shifted from narrow to broad-gaugetracks, or m'ce versa., by the power of a locomotive-engine.

At present the change of the4 wheels from narrow to broad, or from broadto narrow gauge is effected on double rails, which gradually diverge 0rconverge to the desired width. On such ogee lails the cars can not bemoved along by locomotive-engines, which have no adjustable wheels, andconsequently the change has lto be produced by moving each car bymuscular power over the changing rails. This operation is quite tediousand laborious. To facilitate it I have made the ogee rail on one side ofthe track only, and combined it with a switch which will accommodate'itself to the `gauge of the locomotive, so that either a narrow orbroad-gauge engine can be used for spreading or contracting the wheelsof an entire train of cars.

for transferring cars from the narrow to the broad t gauge, or niceversa.

The switch-rail D is connected with a weighted lever, E, by which itwill be held either againstthe rail B 0r against the check-rail F, as infig. l.

G is a check-rail for A.

H, a check-rail for 15, converging with the inner rail D.

The check-rail F of C is gradually bent outwardly to becomefthecheck-rail also of B beyond-the switch.

It' the cars are to be moved from the narrow gauge to the broad theswitch is set against the rail B. The engine can follow or precede thecars on the broad gauge, the switch giving way to it when it approaches;so also a broad-gauge engine can be used for changing the cars from abroad to a narrow gauge, the switch being set in front of the engine tokeep'it on the rail B while the cars are transferred to G.

Having thus described my invention,

I claim as new and desire to secure vby Letters Patent- The combinationof the broad and narrow-gauge rails B and O with the adjustableswitch-rail D, for permitting the transfer of cars from narrow to broadgauge, and cioe versa, as specified.

THOMAS FOGG.
